Half-awake's manga / #Police officer seme(1)

When his interior designer mom takes off to New York for a year, Toranosuke, a senior high school student, gets sent to stay with his uncle Ryouji. It just happens to be his luck that Ryouji is obnoxious, violent, and has the same sharp tongue as his sister! Only, it turns out that Ryouji's not that bad after all, and maybe Tora's even falling in love with him (his uncle, of all people!). Except that Ryouji's pretty much the worst guy in the world to fall for: he enjoys sex more than eating, has a commitment problem, and has long since convinced himself that he's really, really straight. Is this brute with a heart of gold capable of returning Tora's feelings?
